Is there a way to create an alert for loss of DB connectivity. We seem to suffer sporadic Error: Network error IOException: Connection timed out: connect     - the actual agent diagnostic event is what is ideal   It would be good if an alert can be created to advise of this event. In the current health rule options there is no way to do this   Thank you   ... View more

Hi   Wondering if it is possible to create a business transaction group based on node? Reason I ask is that we have 2 legged application (each leg has multiple servers in different data centres) & there is a requirement to monitor the application by site. I can create a view using individual metrics from each server but would like to roll these up into a site metric / business transaction group. Thank you   ... View more
